This is a portable water quality meter compatible with field measurements of pH, ORP, electrical conductivity, and dissolved oxygen!

This is a multi-type portable water quality meter that allows for the measurement of "pH," "ORP," "electrical conductivity," and "dissolved oxygen" through probe replacement. Available in a 2-channel type MM-42DP and a 1-channel type MM-41DP! The measurement of dissolved oxygen adopts an "optical method"! With a waterproof structure and backlight, it can be safely used in the field. ◎ You can view detailed specifications and more from the "PDF Download." If you are interested, please download the catalog to take a look. Additionally, you can download materials that clearly explain the measurement methods for pH, electrical conductivity, and dissolved oxygen.

This is the announcement for the second part of the Op-Amp Classroom Series, "Op-Amp Classroom - DC Characteristics and AC Characteristics." We will explain the DC and AC electrical characteristics as the basics of op-amps. Since we will start with an introduction to fundamental functions, those who have not participated in Op-Amp Classroom 1 are also welcome to join. The difficulty level is beginner to intermediate, so whether you are new to analog ICs or have specific issues, we encourage you to participate! ● Target Audience - Engineers who are new to analog circuit design - Board evaluators and test engineers - Those who are newly responsible for component purchasing ● Agenda 1. Electrical Characteristics of Op-Amps (DC Characteristics) - Input offset voltage / Input bias current - Common-mode input voltage range and input stage configuration - Output inversion of dual-supply op-amps - What are sink/source currents? - Crossover distortion 2. Electrical Characteristics of Op-Amps (AC Characteristics) - What is slew rate? - What is gain-bandwidth product (GBW)? 3. Oscillation of Op-Amps We look forward to your participation!

Nitto Kohki will be exhibiting at the "Data Center EXPO" held at Makuhari Messe Hall 1 from Wednesday, October 23 to Friday, October 25. [Booth Number: A6-23] At this exhibition, we will showcase the "Compact Zero Spill Coupler," which is specifically designed for data centers, including supercomputers. We will also present the "Blind Mate Type," a fitting exclusively for server cooling piping, as a reference exhibit.

On this occasion, we have opened a showroom for Tajima embroidery machines in conjunction with the renovation of the Chūnichi Jūki headquarters building. To commemorate the opening of the showroom, we will hold an exhibition of Tajima embroidery machines.

Next-generation large resin and metal 3D printers that achieve astonishing high-speed molding, low-cost, and high-precision molding are being rapidly introduced to the market. These printers are being utilized in the manufacturing of large parts and products in the aerospace, automotive, industrial machinery, plant, defense, and social infrastructure sectors, as well as in parts and mold repairs and reverse engineering. In this seminar, we will discuss the latest developments and features of cutting-edge machines from Stratasys, the largest manufacturer of large resin 3D printers, and Lobotics, along with domestic and international case studies. We will also explore innovative molding technologies from leading users such as Fujikohsai Industries and Sanko Gosei, who utilize large metal 3D printers from Meltio and Matsuura Machinery to create large metal parts, large metal products, and large mold components. The seminar will provide concrete and easy-to-understand explanations of key points and considerations for implementation and utilization, various manufacturing examples, and discussions on molding size, quality, cost, lead time, and success and failure stories. 3D printers enable the complex integrated molding of multiple parts into a single large shape, which was impossible with previous processing methods and technologies. This capability allows for a significant reduction in the number of parts, achieving short lead times, low costs, high-quality manufacturing, and a reduction in the number of processes and personnel involved.
